FAQ for CP1E-N20DT1-A

What's the advantage of transistor output over relay output?

Transistor outputs offer: much faster switching (up to 100kHz for pulse output), longer life (no mechanical contacts), silent operation, and higher switching frequency. Choose transistor for high-speed counting, positioning, or PWM applications.

What's the difference between NPN (sinking) and PNP (sourcing) outputs?

NPN (sinking) switches the negative/0V side - current flows INTO the output. PNP (sourcing) switches the positive side - current flows OUT of the output. Match your output type to your load wiring and regional standards (NPN common in Asia, PNP common in Europe).

Can I use this PLC for stepper motor control?

Yes, the transistor output model supports 100kHz pulse output for stepper motor control. Use pulse/direction signals to control stepper drivers. Suitable for single-axis positioning applications like indexing tables or linear actuators.

What's the maximum load current for transistor outputs?

0.3A per point, 0.8A per common (4 points). For higher current loads, use intermediate relays or contactors. Total current for all outputs should not exceed 1.2A for the CPU unit.
